WILLIAM K. WILSON AND JOSEPH WALLBILLICI-I, OF NEW ORLEANS, LOUISIANA,

ASSIGNORS TO NEW ORLEANS COEPER WORKS, 013 NEW ORLEANS, LOUISIANA, A

PARTNERSHIP.

STILL.

To all whom it may concern:

Be it known that we, l/VILLIAM K. WVILsoN and JOSEPH IVALLBILLICH, citizens of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Improvement in Stills, of which the following is a specification.

In turpentine and other stills of an analogous character, which we have seen in practical use in the commercial production of turpentine and the like, it is the usual custom to provide the kettle with a single opening in its top over which the cap of the conduit leading to the condensing worm is detachably mounted. This opening has to do duty both for charging and skimming and permitting the passage of the vapors to be condensed into the conduit or worm. As a result the cap must be detachable, and leakage about the same when it is in place, ordinarily has to be' prevented by packings of clay or analogous material. Furthermore the connection of the cap with the worm in like manner has to be detachable and packed.

The primary object of the present invention is to provide novel, simple and effective means whereby the cap or conduit can be permanently connected to a still kettle having an oblong upstanding neck, separate means being provided for giving access to the still through the neck, said means thus permitting the introduction of the material without dismembering the structure and also giving better access to the surface of the con tents of the kettle for the purpose of skimming the same.

A further and important object is to provide means which will protect the cap or conduit from injury during the charging operation.

An embodiment of the invention that is at present considered the preferable one is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of the still. Fig. 2 is a cross sectional view through a portion of the same on an enlarged scale. Fig. 3 is a vertical sectional view through the upper portion of the kettle and the associated mechanism. Fig. 4: is a sectional .view on the line 1-4 of Fig. 3.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

Serial No. 439,355.

In the embodiment disclosed, the still body is in the form of a kettle5 having the usual discharge spout 6 projecting from its lower portion. This body or kettle has an upstanding neck 7, which as clearly shown in Flg. 2, is oblong, and preferably elliptlcal. Secured to the upper margin of the neck 7 is an angle iron 8 forming an outstanding flange 9, and resting on this flange, is a closure plate 10 that covers the top of the neck, and is suitably secured thereto by bolts, rivets or other fasteners 11. The closure or cover plate 10 corresponds in shape to the neck, and is provided in its end portions with circular openings 12 and 13, the latter being preferably surrounded by an upstanding rib 14.

Any suitable form of condenser may be employed, and in the present embodiment, a coil 15 is illustrated, to the upper end of which is connected a conduit 16. The inlet end of the conduit is in the form of a cap 17 that communicates with the opening 12, and has an outstanding flange 18 resting on the closure plate 10 and permanently fastened thereto. By the term permanently fastened, it will of course be understood that it does not have to be removed after each operation of the still, and therefore the fastening means can be in the form of bolts or other devices so that for the purpose of repair or renewal, the said cap can be removed.

A cap or closure disk 19 is provided for the opening 13 and rests upon the rib 14, as shown.

Interposed between the openings 12 and 13 and extending alongside the cap 17, is a guard or shield in the form of a curved plate 20, that has its lower margin secured to an upstanding flange 21 carried by the plate 10. In the lower portion of this shield or guard is formed a socket 22 in which is detachably engaged one end of a holding bar 23 that extends over the closure cap 19, and has its other end formed into a hook 24 that engages beneath the flange 9. A clamping screw 25 is threaded through the central portion of the bar, and bears upon the center of the cap. The upper end of this screw is provided with an eye 26 to receive a bar for turning the same, though it may be constructed in any suitable manner so that it can be readily operated.

It will be evident from this structure that inasmuch as an opening 13 is provided separate from the opening 12 through which vaporous products pass, the charging of the still can be accomplished without the mess sity of detaching the cap 17. Moreover the contents can be skimmed whenever desired, and this skimmingoperation can be performed with greater ease and with better effect, because of the upstanding elongated neck that is provided. The crude or pine gum, which is placed in the kettle or still 5, usually contains leaves, chips or the like, so that after the gum melts, it is necessary to skim off the leaves and chips, else the resulting rosin will be discolored and other wise objectionably affected. The peculiar shape of the neck or collar 7 facilitates this skimming operation, since the said neck constitutes a well into which the leaves, bark and the like will collect in rising to the top of the gum after the same becomes liquid by the heating. It will thus be seen that the foreign matter to be skimmed off is concentrated in a small area within convenient reach of the operator or distiller. This skimming can be accomplished without loss of vapor or danger to the distiller from suffocating, it being a demonstrated fact that substantially all the vapor passes off from the still through the chamber or cap 17.

T heshield or guard 20 protects the cap 17 from injury, as it prevents barrels or other containers for the material to be treated striking the same during the filling operation, and this guard or shield furthermore acts as holding means for one end of the bar It will be noted that this shield or guard 20 is rigid and is spaced from the vapor conduit. These vapor conduits or goose necks are usually of copper and are expensive, hence, very great care must be taken to prevent any marring or breaking of the dome or cap of the vapor conduit. This is very liable to occur when the barrels or buckets containing the material to be dis tilled are placed in position upon the cover plate so as to empty into the filling opening. Under the circumstances of use where the barrels or buckets are lifted quickly and where much care cannot be exercised, it is imperative that some means of guarding the dome of the vapor conduit be used. It will also be noted that the guard or shield 20 is curved at its ends away from the filling opening. This is necessary because the barrels or buckets used in filling, being larger in diameter than the diameter of the filling opening, project laterally, and, hence, a fiat or straight guard would not permit the mid dle of the barrel to coincide with the middle of the filling opening unless the barrel were presented from the end of the still, which very often is not convenient.

The advantages of our invention lie not only in the fact that the material being distilled can be skimmed and otherwise treated without dismembering the still head from the body, but resides also in the fact that we have produced a cover plate provided with means whereby it may be attached to a still of an ordinary type, and to the ordinary goose necks or vapor conduits already in use in the art.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
